Diarmuid O'Neill and Patrick O'Malley are both pseudonyms used by Dominic Behan (on this album.)
Bruce Eder, All Music Guide: "As to the singers themselves, there's always been a matter of conjecture regarding who appears on this record; Enoch Kent is still performing as of 2009, 46 years after it was made, but no one was ever sure who Diarmuid O'Neill or Patrick O'Malley were. And it has been rumored (and never denied or refuted) since this album's release in 1963 that they were one and the same man, and that man was actually Dominic Behan, the author, activist, and composer best known for 'The Patriot Game'."
Above is one example of Dominic Behan's "rumored" particapation on this album. Perhaps people (such as Bruce Eder) aren't very familiar with Dominic's vocals — to me, there is no question, that it is indeed Dominic Behan.
